Description

BACKGROUND

Schools, homeowners, tradesmen, and many others in the workforce employ a pencil as their writing and marking instrument. Often times, the handler may be on a ladder, scaffolding, or another elevated structure and happen to misplace or break the pencil, or too often is left with an unsharpened utensil. Conversely, some focused hobbies and/or responsibilities sanction the need for a device which serves multiple purposes allowing the individual to concentrate on the task at hand. As such, the convenience, accessibility, and condition of a writing utensil are integral, yet credulous components of completing the task at hand. The design of this device provides a practical and functional all-encompassing instrument illustrating convenience, accessibility, and usability of multiple types, sizes, and shapes of pencils and other exemplary embodiments. This invention is an improvement as there is no other all-in-one pencil sharpening device with a retractable pencil holder.

SUMMARY

Ideal and varying sharpener types accompany a retractable pencil holder which accommodates a writing or marking utensil for any undertaking. Depending on which pencil type is desired, the respective sharpener adheres to the retractable reel. The pencils that may be used consist of multiple shapes, sizes, and characteristics, including but not limited to: carpenter, round, triangular, or hexagonal. When a carpenter pencil is used, the sharpener will possess a single-hole fit to that type of pencil. Use of round, hexagonal, triangular pencils may present a single or dual-holed sharpener, one of a smaller diameter and the other of a larger diameter. The sharpener may or may not have a cover to catch shavings, and the sharpener can be in the form of either an angle and/or flat sharpening composition.

Additionally, this pencil sharpening device with retractable reel conveniently will affix to any type of glove, or other exemplary embodiments. Furthermore, this exemplary embodiment may implore a glove manufactured with the pencil sharpening device with retractable pencil holder already attached, or can be manufactured to affix to a glove and other articles of the like. A flick of the wrist projects the pencil conveniently between the thumb and index finger. The sharpening holes must be placed inward, facing the other hand to easily sharpen the pencil with a free hand.

The retractable reel may be either round, rectangular, or square, by which a similarly shaped sharpener will adhere to said retractable reel. The reverse side of retractable reel may have either a metal or a spring tension clip, alligator clip, adhesive, magnet, or another fastening device to affix to clothing, devices, or surfaces. The cable at the end of the retractable reel employs a rubber fastening device complete with bore to insert the end of the pencil. This rubber embodiment is self-forming and will accept multiple diameter, sizes, and composition of pencils or other exemplary embodiments.
